The skip-nfc framework is available at https://github.com/skiptools/skip-nfc.git, which can be checked out and tested with skip test
once Skip is installed.
SkipNFC
This package provides rudimentary support for Android and iOS NFC interaction for Skip apps.
Usage
let nfcAdapter: NFCAdapter = NFCAdapter()
nfcAdapter.startScanning { message in
print("received message: \(message)")
}
nfcAdapter.stopScanning()
Setup
Android
- Add android.permission.NFC to your
AndroidManifest.xml
.
iOS
- Add Near Field Communication Tag Reader Session Formats Entitlements to your entitlements.
- Add NFCReaderUsageDescription to your
Darwin/Info.plist
. - Add com.apple.developer.nfc.readersession.iso7816.select-identifiers to your
Darwin/Info.plist
as needed.
For example:
<key>com.apple.developer.nfc.readersession.formats</key>
<array>
<string>NDEF</string>
</array>
<key>NSNFCReaderUsageDescription</key>
<string>This app requires access to NFC to read and write data to NFC tags.</string>
Building
This project is a free Swift Package Manager module that uses the Skip plugin to transpile Swift into Kotlin.
Building the module requires that Skip be installed using
Homebrew with brew install skiptools/skip/skip
.
This will also install the necessary build prerequisites:
Kotlin, Gradle, and the Android build tools.
Testing
The module can be tested using the standard swift test
command
or by running the test target for the macOS destination in Xcode,
which will run the Swift tests as well as the transpiled
Kotlin JUnit tests in the Robolectric Android simulation environment.
Parity testing can be performed with skip test
,
which will output a table of the test results for both platforms.
