+pod 'SwiftAudio', '~> 0.11.0'
 ```

 ### Carthage
 SwiftAudio supports [Carthage](https://github.com/Carthage/Carthage). Add this to your Cartfile:
 ```ruby
-github "jorgenhenrichsen/SwiftAudio" ~> 0.9.2
+github "jorgenhenrichsen/SwiftAudio" ~> 0.11.0
 ```
 Then follow the rest of Carthage instructions on [adding a framework](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application).

Jørgen Henrichsen	f31b52f81b	Make the ready state reachable for items with initial time. Fixes a problem where the .ready state would not be reached for audio items that had an initial time.	2019-07-03 14:25:43 +02:00
Jørgen Henrichsen	355c729078	Update README. Update podspec. Bump version to 0.10.0.	2019-07-03 13:22:27 +02:00
Jørgen Henrichsen	719d3c852b	Add an activityindicator to the example. Shows how an activityindicator can be used to indicate loading, when player is loading or buffering.	2019-07-03 13:21:41 +02:00
Jørgen Henrichsen	4f33d7e688	Add a new state `buffering`. Introduces an additional state to better describe the current state of the player. Previously the player would be `idle` until the item was loaded, then changing to `ready`. When the player started to play it would first enter `loading`, then subsequently `playing`. Now it will instead immediately enter `loading`, then when the item is loaded it will enter `ready`. When the item then is played it will enter `buffering` and then `playing`. This should make it easier to update UI accordingly to the players current state.	2019-07-03 11:23:10 +02:00

Jørgen Henrichsen	92bf0b96b6	Remove cancelloading in the load method. This was already done in the reset(soft:) method. Removed the nil check before canceling the pendingAsset load, since the coalescing `?` operator was already used anyway.	2019-06-23 18:13:48 +02:00
Jørgen Henrichsen	457dff7c01	Use weak capturing of the AudioPlayer. Remove initial time test. Weak capturing of the AudioPlayer is done in the listener callback functions in order to not receive INVOPs in the event the audioPlayer is deallocated. The initial time test is removed because of the unreliable results it produces.	2019-06-23 18:06:43 +02:00
