Steps to Reproduce

1. step 1

At step pod install came out this error [!] Unable to determine Swift version for the following pods:

• react-native-ble-plx-swift does not specify a Swift version and none of the targets (myapp2) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.

Solve

According to this issue https://github.com/CocoaPods/CocoaPods/issues/7327 I modified react-native-ble-plx-swift.podspec one line code s.pod_target_xcconfig = { ‘SWIFT_VERSION’ => ‘4.1’ } --> s.swift_version = “4.1” And it works for me

Here’s the code

` require ‘json’

package = JSON.parse(File.read(File.join(dir, ‘package.json’)))

Pod::Spec.new do |s| s.name = “react-native-ble-plx-swift” s.version = package[‘version’] s.summary = “React Native Bluetooth Low Energy library - Swift static library”

s.authors = { “Przemysław Lenart” => “[e-mail]” } s.homepage = “https://github.com/Polidea/react-native-ble-plx#readme” s.license = “Apache License 2.0” s.platform = :ios, “8.0”

s.source = { :git => “https://github.com/Polidea/react-native-ble-plx.git” } s.source_files = “ios/**/*.{swift}” s.swift_version = “4.1” end `

Context

• Library version: 1.0.3
• Platform: Android/iOS
• Platform logs (logcat/XCode):10.2,1

I discovered this thread https://github.com/kiwi-bop/flutter_crashlytics/issues/22 and the solution of adding a new Swift file in the project fixed the issue for me

Just to bump this up. I am also having the exact issue.
