从 Xcode11 开始,我们一直在从 CocoaPods 迁移到 SwiftPM。不幸的是,一些依赖项还没有 SwiftPM 支持。像火力基地。
这不是一个真正的问题,因为它们可以彼此相邻共存。
但是自从(我认为 Firebase iOS SDK v6.13.0)他们添加了对PromisesObjC
.
这本身不是问题,但我们的大多数项目(和(子)依赖项)都使用谷歌通过 SwiftPm 的承诺。
现在的问题是Promises SwiftPM 依赖项和Firebase CocoaPods 都使用FBLPromises,这将导致以下错误:
duplicate symbol '_FBLPromiseRetryDefaultAttemptsCount' in:
/path/Products/Debug-iphonesimulator/FBLPromises.o
/path/Products/Debug-iphonesimulator/PromisesObjC/libPromisesObjC.a(FBLPromise+Retry.o)

目前解决此问题的唯一方法是将Firebase CocoaPods depenceny 设置为v6.11.0
我当前的Podfile:
source 'git@github.com:CocoaPods/Specs.git'
workspace 'Workspace'
platform :ios, '11.0'
use_modular_headers!
inhibit_all_warnings!
install! 'cocoapods',
:generate_multiple_pod_projects => true,
:incremental_installation => true
target 'HandpickedFamilyApp' do
pod 'Firebase/Core'
pod 'Firebase/RemoteConfig'
pod 'Firebase/Analytics'
pod 'Firebase/Performance'
pod 'Fabric'
pod 'Crashlytics'
pod 'SwiftLint'
script_phase :name => 'Run Fabric',
:script => '"${PODS_ROOT}/Fabric/run"',
:input_files => ['$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)']
end
