Kotlin/Native Build Performance
Turn "the iOS build is slow" into a measured diagnosis and a small set of safe fixes. Two rules apply throughout:
- Never trade away required release behavior. A faster local loop must not change what CI publishes.
- Measure before and after with the same command and the same build state. An unmeasured fix is a guess.
Step 0: Classify the Slow Scenario
Establish four facts before editing anything: where (local or CI), what (debug feedback loop or release/distribution artifact), state (first build, clean, warm, or no-op), and phase (which tasks dominate the log). Then match the dominant symptom:
| Symptom in the build log | Likely cause | Read |
|---|---|---|
linkRelease* or *ReleaseXCFramework tasks in a local development loop | Building distribution artifacts for development | artifacts-and-targets |
| Kotlin/Native compiler distribution downloaded on every CI run | ~/.konan not preserved between runs | caching-and-gradle |
| Long pause before the first task starts | Configuration phase, no configuration cache | caching-and-gradle |
| All iOS targets build when only one simulator is needed | Broad task (build, assemble, assemble*XCFramework) or unused targets | artifacts-and-targets |
ksp* tasks ahead of compileKotlinIos* | Generated-code work on the native path | exports-and-generated-code |
| Small source edit recompiles and relinks everything | Compiler caches disabled, or missing incrementality | caching-and-gradle, experimental |
Machine overloaded while several link* tasks run at once | Parallel native linking | caching-and-gradle, worker-limit caveat |
Step 1: Audit and Measure
-
Run the static audit from the project root:
scripts/audit-native-build.sh /path/to/projectIt is read-only and prints
file:linefindings (disabled caches, broad local tasks,transitiveExport, broad KSP configuration, missing CI.konancache), each pointing at the reference file with the fix. Findings are leads, not verdicts — confirm each against project policy. -
Find the command the user actually waits for: a script, a CI step, or the Gradle invocation inside an Xcode build phase. Optimize that command, not a task you picked yourself.
-
Run it twice when practical. The first build downloads Kotlin/Native components and fills caches; only the second and later runs are representative. Attribute time per task before blaming the compiler:
kotlin.build.report.output=file # writes build/reports/kotlin-build/Gradle's
--scanor--profilework too. -
If you cannot run the build (no macOS host, no Xcode), analyze logs, build scans, or checked-in metrics instead — and state explicitly that the conclusion is static.
Step 2: Fix in Safe Order
Apply fixes one at a time, re-measuring as you go:
- Restore healthy defaults — remove cache/daemon workarounds, enable
Gradle build and configuration caches, keep
~/.konanwarm in CI, update Kotlin: references/caching-and-gradle.md - Build only what the feedback loop needs — one specific task per loop, correct integration method, justified target matrix: references/artifacts-and-targets.md
- Cut export and generated-code cost — drop
transitiveExport, narrowexport(...), scope KSP work to the native compilations that need it: references/exports-and-generated-code.md - Experimental switches last, with the user's agreement: references/experimental.md
Worked Example
A developer on an Apple Silicon Mac complains that "every shared-module
change costs 12 minutes". Their loop runs ./gradlew :shared:assembleXCFramework.
A build scan of the second (warm) run shows:
:shared:linkReleaseFrameworkIosArm64 348s
:shared:linkReleaseFrameworkIosX64 341s
:shared:compileKotlinIosX64 96s
:shared:linkDebugFrameworkIosSimulatorArm64 41s
:shared:compileKotlinIosSimulatorArm64 38s
configuration phase 64s
Reasoning chain:
- The loop is local + debug + warm, but ~690s goes to
linkRelease*— release linking is an order of magnitude slower than debug and only CI needs it. Replace the local command with:shared:linkDebugFrameworkIosSimulatorArm64(or the Xcode embed task if Xcode drives the build). (artifacts-and-targets) - All
iosX64work serves Intel simulators; ask whether the team still supports them before removing the target. (artifacts-and-targets) - 64s of configuration on every run disappears behind
org.gradle.configuration-cache=trueonce trialed. (caching-and-gradle) - Expected loop after the change: ~40s compile + ~40s link on warm builds — confirm by re-running the new command twice and comparing.
- CI keeps
assembleXCFrameworkuntouched; note that explicitly in the report.
Verify
- Re-run the exact baseline command; compare warm build against warm build, not warm against cold.
- Second run with the configuration cache reports it is being reused.
- The local development log no longer contains
linkRelease*,*ReleaseXCFramework, or removed generator tasks. - CI still produces every required release artifact, unchanged.
- Tests pass and the app still runs from Xcode.
-
scripts/audit-native-build.shreports no findings you have not consciously accepted and documented.

# Kotlin/Native Build Performance
Turn "the iOS build is slow" into a measured diagnosis and a small set of safe
fixes. Two rules apply throughout:
1. Never trade away required release behavior. A faster local loop must not
change what CI publishes.
2. Measure before and after with the same command and the same build state.
An unmeasured fix is a guess.
## Step 0: Classify the Slow Scenario
Establish four facts before editing anything: **where** (local or CI),
**what** (debug feedback loop or release/distribution artifact), **state**
(first build, clean, warm, or no-op), and **phase** (which tasks dominate the
log). Then match the dominant symptom:
| Symptom in the build log | Likely cause | Read |
|---|---|---|
| `linkRelease*` or `*ReleaseXCFramework` tasks in a local development loop | Building distribution artifacts for development | [artifacts-and-targets](references/artifacts-and-targets.md) |
| Kotlin/Native compiler distribution downloaded on every CI run | `~/.konan` not preserved between runs | [caching-and-gradle](references/caching-and-gradle.md) |
| Long pause before the first task starts | Configuration phase, no configuration cache | [caching-and-gradle](references/caching-and-gradle.md) |
| All iOS targets build when only one simulator is needed | Broad task (`build`, `assemble`, `assemble*XCFramework`) or unused targets | [artifacts-and-targets](references/artifacts-and-targets.md) |
| `ksp*` tasks ahead of `compileKotlinIos*` | Generated-code work on the native path | [exports-and-generated-code](references/exports-and-generated-code.md) |
| Small source edit recompiles and relinks everything | Compiler caches disabled, or missing incrementality | [caching-and-gradle](references/caching-and-gradle.md), [experimental](references/experimental.md) |
| Machine overloaded while several `link*` tasks run at once | Parallel native linking | [caching-and-gradle](references/caching-and-gradle.md), worker-limit caveat |
## Step 1: Audit and Measure
1. Run the static audit from the project root:
```bash
scripts/audit-native-build.sh /path/to/project
```
It is read-only and prints `file:line` findings (disabled caches, broad
local tasks, `transitiveExport`, broad KSP configuration, missing CI
`.konan` cache), each pointing at the reference file with the fix.
Findings are leads, not verdicts — confirm each against project policy.
2. Find the command the user actually waits for: a script, a CI step, or the
Gradle invocation inside an Xcode build phase. Optimize that command, not
a task you picked yourself.
3. Run it twice when practical. The first build downloads Kotlin/Native
components and fills caches; only the second and later runs are
representative. Attribute time per task before blaming the compiler:
```properties
kotlin.build.report.output=file # writes build/reports/kotlin-build/
```
Gradle's `--scan` or `--profile` work too.
4. If you cannot run the build (no macOS host, no Xcode), analyze logs, build
scans, or checked-in metrics instead — and state explicitly that the
conclusion is static.
## Step 2: Fix in Safe Order
Apply fixes one at a time, re-measuring as you go:
1. **Restore healthy defaults** — remove cache/daemon workarounds, enable
Gradle build and configuration caches, keep `~/.konan` warm in CI, update
Kotlin: [references/caching-and-gradle.md](references/caching-and-gradle.md)
2. **Build only what the feedback loop needs** — one specific task per loop,
correct integration method, justified target matrix:
[references/artifacts-and-targets.md](references/artifacts-and-targets.md)
3. **Cut export and generated-code cost** — drop `transitiveExport`, narrow
`export(...)`, scope KSP work to the native compilations that need it:
[references/exports-and-generated-code.md](references/exports-and-generated-code.md)
4. **Experimental switches last, with the user's agreement**:
[references/experimental.md](references/experimental.md)
## Worked Example
A developer on an Apple Silicon Mac complains that "every shared-module
change costs 12 minutes". Their loop runs `./gradlew :shared:assembleXCFramework`.
A build scan of the second (warm) run shows:
```
:shared:linkReleaseFrameworkIosArm64 348s
:shared:linkReleaseFrameworkIosX64 341s
:shared:compileKotlinIosX64 96s
:shared:linkDebugFrameworkIosSimulatorArm64 41s
:shared:compileKotlinIosSimulatorArm64 38s
configuration phase 64s
```
Reasoning chain:
- The loop is **local + debug + warm**, but ~690s goes to `linkRelease*` —
release linking is an order of magnitude slower than debug and only CI
needs it. Replace the local command with
`:shared:linkDebugFrameworkIosSimulatorArm64` (or the Xcode embed task if
Xcode drives the build). *(artifacts-and-targets)*
- All `iosX64` work serves Intel simulators; ask whether the team still
supports them before removing the target. *(artifacts-and-targets)*
- 64s of configuration on every run disappears behind
`org.gradle.configuration-cache=true` once trialed. *(caching-and-gradle)*
- Expected loop after the change: ~40s compile + ~40s link on warm builds —
confirm by re-running the new command twice and comparing.
- CI keeps `assembleXCFramework` untouched; note that explicitly in the
report.
## Verify
- [ ] Re-run the exact baseline command; compare warm build against warm
build, not warm against cold.
- [ ] Second run with the configuration cache reports it is being reused.
- [ ] The local development log no longer contains `linkRelease*`,
`*ReleaseXCFramework`, or removed generator tasks.
- [ ] CI still produces every required release artifact, unchanged.
- [ ] Tests pass and the app still runs from Xcode.
- [ ] `scripts/audit-native-build.sh` reports no findings you have not
consciously accepted and documented.
