Bug: Generated iOS projects only support iossimulator

[erikkerber]

Describe the bug

Generated iOS apps set SUPPORTED_PLATFORMS to iphonesimulator, omitting iphoneos. This prevents debugging to an iOS device

Reproduction steps

cd examples/ios_app
bazel run :xcodeproj

Expected behavior

SUPPORTED_PLATFORMS is set to iphonesimulator iphoneos

Versions

• Bazel: 5.1.0
• rules_xcodeproj: b5e86b2
• rules_apple:
• rules_swift:

Additional context

[jpsim]

FYI I added #285 to track device support and documented some workarounds in #285 (comment) and in the documentation in envoyproxy/envoy-mobile#2263

@jpsim Was that using BwB or BwX? I should clarify this is using BwX, and it shouldn't need any additional Bazel settings to run.

[jpsim]

Ultimately I'm using BwB for Envoy Mobile, but the --ios_multi_cpus=arm64 change also generated a project that could build to a device when using BwX.

That being said, it does seem to me that whenever SUPPORTED_PLATFORMS is set to iphonesimulator, we could also add iphoneos.

[erikkerber]

OK yeah there are downstream problems if this changes, and that has to do with how the BazelDependencies files are generated.

Will leave this open until @brentleyjones returns just in case the BwX element of this that cares about that build setting is worthy of a different issue.

[brentleyjones]

This is intended. It's the first in my list to support device in addition to simulator in a single project generation.

For now you can change your bazelrc to point to device and it will generate for device.
