Upgrade to Capacitor beta.17 about generic-oauth2

[moberwasserlechner]

I introduce peerDependencies because the plugin does not need a specific Capacitor version right know every version greater than beta.11 is ok.

As I'm working on the ios part I realized that beta.17 is needed because cap moved to Swift 4.2

Docs for the next upgrade of Capacitor:

Use concrete version of Capacitor in

• https://github.com/moberwasserlechner/capacitor-oauth2/blob/master/ByteowlsCapacitorOauth2.podspec#L14
• https://github.com/moberwasserlechner/capacitor-oauth2/blob/master/ios/ByteowlsCapacitorOauth2/Podfile#L10
  I will not use wildcard versions because I get unintentional updates in the libs.

Check if Swift Language version matches Capacitor and change accordingly in

• XCode / Build Settings / Swift Compiler - Language
• https://github.com/moberwasserlechner/capacitor-oauth2/blob/master/ByteowlsCapacitorOauth2.podspec#L18

After changing the dependencies do

• Clean the cocoapod cache pod cache clean --all
• Update the cocoapod sudo gem install cocoapods
• Update the local cocoapod repository with the changes fromt he master pod update
• If that does not work remove the Podfile.lock and run pod install

In XCode

• Always clean Build (Cmd + Shift + K) :)
