Getting Up To Speed With NativeScript 2.3, Xcode 8 and iOS 10

tns livesync ios --emulator --watch

Unsupported version Xcode 8

Oh no …

It’s That Time

The iPhone 7 is out along with iOS 10 and things have changed.  It hit me today when I was toying with my company’s app for the first time since upgrading Xcode.

So what do? Well, the first thing I needed to solve was getting my apps running in Simulator again.  I opened up Xcode and built my app in there instead of the command line tns.  I ran it on iPhone 7 Simulator and everything popped up and seemed to be working until it crashed right away on launch.

Upgrade NativeScript to “Next”

I uninstalled NS and the tns modules and reinstalled completely using the next version (2.4).

npm uninstall nativescript -g
npm uninstall tns-core-modules
npm install nativescript@next -g
npm install tns-core-modules@next

Then I removed the ios platform from my app and added it back.  Voila, things were loading up.  Thing is, I’m lying a little, I forgot to install the @next version of tns-core-modules and even though the app was opening certain things weren’t working like trying to set the src of an Image via javascript.

Properties Not Methods

So something big is happening.  Xcode is changing some big core items from using methods to initiate and instead using properties.  For example I use local-notifications plugin to send phone notifications.  I was erroring out with:

NSNotificationCenter.defaultCenter() is not a function

Apparently that is now a property so I had to adjust the module’s code in local-notifications.ios.js to

NSNotificationCenter.defaultCenter

And it works just fine now.  Or so I believe, no more errors but haven’t tested it thoroughly.

plist.info Permission Changes

Next the app crashes when I try to open the camera.  I’m getting errors saying there’s permission issues.  Turns out I need to have some new info in app/App_Resources/plist.info

<key>NSPhotoLibraryUsageDescription</key>
<string>Photo Library Access Warning</string>

More To Come

This is all so far but I’ll be sure to add more information as I encounter it.
