iOS: Enterprise build with over the air install support using Fastlane - ios

Question

I am trying to configure my Fastfile to get an enterprise build with over the air installation support. Here is my current lane:
lane :enterprise do
increment_build_number(xcodeproj: "myapp.xcodeproj")
build_app(
scheme: "enterprise",
output_name: "myapp.ipa",
output_directory: "build",
export_options: {
manifest: {
appURL: "my app url",
displayImageURL: "display image url",
fullSizeImageURL: "full size image url"
}
},
export_method: "enterprise",
export_xcargs: "-allowProvisioningUpdates"
)
end
The build runs withouth problem and I get both ipa and manifest.plist ffiles. The problem is when get the build with Xcode, it produces 5 files:
DistributionSummary.plist
ExportOptions.plist
manifest.plist
Packaging.log
myapp.ipa
When I try to update the files by just changing ipa and the plist files, over the air intallation failes wih this error:
Error Domain=MIInstallerErrorDomain Code=13
"Failed to verify code signature of /.../myapp.app : 0xe8008017
(A signed resource has been added, modified, or deleted.)"
UserInfo={
NSLocalizedDescription=Failed to verify code signature of /.../myapp.app : 0xe8008017

FunctionName=+[MICodeSigningVerifier _validateSignatureAndCopyInfoForURL:withOptions:error:],
SourceFileLine=77,
LibMISErrorNumber=-402620393
}
for bundle IDs ("com.myapp")
How can I make Fastlane generate all these files?
UPDATE
I have managed to get DistributionSummary.plist and ExportOptions.plistusing below code:
fastlane_require "gym"
dist_plist_path = File.join(Gym.cache[:temporary_output_path], "DistributionSummary.plist")
FileUtils.cp(dist_plist_path, "../build")
dist_plist_path = File.join(Gym.cache[:temporary_output_path], "ExportOptions.plist")
FileUtils.cp(dist_plist_path, "../build")
But I am still getting error when I try to install the app.

I have tried deleting all the files except ipa and manifest with Xcode export and It is still working except it doesn't show app icon while downloading the app. So the error I am getting isn't related to other files.

Answer 1

I have found the problem. My app name contains a non ASCII character "ö" and it cousing the problem when I try to get an enterprise export. I gess enterprise package validation doesn't handle non ASCII characters. After changing the character the problem is solved.
