Build failed on iOS (SWIFT_VERSION)

Hi,

the example works fine. But when I tried to compile my own project, the following error occurred:

	Error output from Xcode build:
	↳
	    ** BUILD FAILED **
	    
	Xcode's output:
	↳
	    === BUILD TARGET contacts_service OF PROJECT Pods WITH CONFIGURATION Debug ===
	    The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift. This setting can be set in the build settings editor.
Could not build the precompiled application for the device.

I figured out, that the solution/ workaround is to change the configuration in “ios/Runner.xcodeproj/project.pbxproj”: from VERSIONING_SYSTEM = "apple-generic"; to

SWIFT_SWIFT3_OBJC_INFERENCE=On;
SWIFT_VERSION=4.0;

Is there a dependency compiled in an earlier swift version that could be updated?

Best, Marcus

@blaneyneil seems a “non issue”, do you bootstrap the flutter project using swift? Since this plugin use swift you need to use -i flutter flag when do you create a project. No solution to add swift support on already running project, the suggested solution is to:

• create a new project with the same name in a different folder including swift support
• backup your ios folder
• replace current ios folder with the ios folder created from new project that include swift support

I tested it and work like a charm (see other issue), eg (supposing your project is awesome_project):

$ ls .
awesome_project
$ mkdir test
$ cd test
$ flutter create -i swift awesome_project
$ cd ..
$ mv awesome_project/ios awesome_project/ios_bak
$ mv test/awesome_project/ios awesome_project/ios
$ rm -rf test
$ cd awesome_project
$ flutter packages get

than edit the ios/Runner/Info.plist to include permission and rebuild your flutter project.

Do what Mavimo suggested or you can simply remove ios folder and run this command $ flutter create -i swift .

This will rebuild the project with swift integration
