+# 👨🏻‍💻 SwiftEntitlements
+
+📱 This is a simple Swift utility package that reads application entitlements for you. 
+
+## Features
+
+✅ Reading entitlements from iOS Application binary
+
+### Note
+⚠️ The library currently does not support reading entitlements from fat Mach-O file. If that is your use-case - please let me know. 
+
+## Usage
+
+Library exposes ``entitlements`` property on UIApplication instances. 
+
+```
+public extension UIApplication {
+    public var entitlements: Entitlements { get }
+}
+```
+Library provides a set of predefines keys for most common entitlements keys as described in [Apple docs](https://developer.apple.com/documentation/bundleresources/entitlements). Please see ```Entitlements.Keys``` to check available options.
+
+Instance of Entitlements class exposes simple API for getting values
+```
+let value = UIApplication.shared.entitlements.value(forKey: .apsEnvironment) as? String
+```
+If the required key is not present - it could be easily defined.
+```
+let myAwesomeKey = Entitlements.Key("some.awesome.key")
+let value = UIApplication.shared.entitlements.value(forKey: myAwesomeKey)
+```
