# XCode will error during it's dependency graph construction (which happens before the build
|
|
# stage starts and any target "Run Script" phases are triggered)
|
|
#
|
|
# In order to avoid this error we need to build the framework before actually getting to the
|
|
# build stage so XCode is able to build the dependency graph
|
|
#
|
|
# XCode's Pre-action scripts don't output anything into XCode so the only way to emit a useful
|
|
# error is to **return a success status** and have the project detect and log the error itself
|
|
# then log it, stopping the build at that point
|
|
#
|
|
# The other step to get this to work properly is to ensure the framework in "Link Binary with
|
|
# Libraries" isn't using a relative directory, unfortunately there doesn't seem to be a good
|
|
# way to do this directly so we need to modify the '.pbxproj' file directly, updating the
|
|
# framework entry to have the following (on a single line):
|
|
# {
|
|
# isa = PBXFileReference;
|
|
# explicitFileType = wrapper.xcframework;
|
|
# includeInIndex = 0;
|
|
# path = "{FRAMEWORK NAME GOES HERE}";
|
|
# sourceTree = BUILD_DIR;
|
|
# };
|
|
#
|
|
# Note: We might one day be able to replace this with a local podspec if this GitHub feature
|
|
# request ever gets implemented: https://github.com/CocoaPods/CocoaPods/issues/8464
