nfc writer ios app

nfc writer app is a hacky fun side project that writes twitter and contact (links) to writable nfcs. runs on iPhone 7+ iOS 14+. join the testflight

this app should have been built this in SwiftUI, but I really wanted to play with diffable data source (yes, extreemly easy and flexible).

had fun exploring:

• UITableViewDiffableDataSource
• NSDiffableDataSourceSnapshot
• UIListContentConfiguration
• CoreNFC
• Contacts

did not have fun (finding bug workarounds):

• ContactsUI
• UISearchController

getting started

• firebase storage: enables contacts via links

• swiftlint: lint

• fastlane: automate build and release

xcode command line tools (macOS)

xcode-select --install 

install dependencies via homebrew

brew install fastlane swiftlint

fastlane setup

fastlane init

config linting @ .swiftlint.yml
