Lightning Network is slowly developing and it is crucial for mainstream acceptance of Bitcoin in my opinion. Swift Lightning Project is IOS App built on top of Lightning Network and it is huge step forward for Bitcoin. Using Lightning Network is very complicated for average user at moment and we need to reach point when somebody use LN without even knowing that. That will happen for sure and projects like Swift Lightning are steps toward that point.
