Reinstall xcode 10, and such a mistake

Why?

[kashban]

I already made a Pull request to fix this:

#428

[lynzz]

@kashban Thanks, why would I use xcode 9.4 reported that such a mistake，for macOS 10.14.1 Beta ?

[kashban]

There was an update for the xcode build tools not long ago which was also issued for XCode 10 (not beta), breaking the same stuff. Perhaps it's not bound to Xcode 10.1 beta.

[lynzz]

@kashban I merged your PR code, the same error occurs

[kashban]

@lynzz Then your error stems from another source. I am on vacation right now and will be back at Oct 22th.

Please post the complete stack trace of this error into your ticket.

[csabbey]

I'm getting the below stack trace. My list-emulator-build-targets line 54 is:
device.availability.toLowerCase().indexOf('unavailable') < 0

It looks like the device availability property got renamed to isAvailable; here's one of the devices:

{ state: 'Shutdown',
  isAvailable: 'YES',
  name: 'iPad Pro (12.9-inch)',
  udid: '5A707375-7596-4375-9A7A-75690B681B46',
  availabilityError: '' }

... and here's the promised stack trace:

[kashban]

That's exactly the issue my PR fixes.

[csabbey]

@kashban Yes, it looks like the same issue.

[waflessnet]

@csabbey , yes, i change the "if" line 54 of platforms/ios/cordova/lib/list-emulator-build-targets for:

if (device.name === deviceType.name.replace(/\-inch/g, ' inch') &&  device.isAvailable == 'YES') 

then, the function "availableDevices" is:

 var availableDevices = Object.keys(devices).reduce(function (availAcc, deviceCategory) {
                var availableDevicesInCategory = devices[deviceCategory];
                availableDevicesInCategory.forEach(function (device) {
                        //console.log(device);
                    if (device.name === deviceType.name.replace(/\-inch/g, ' inch') && device.isAvailable == 'YES') {
                            availAcc.push(device);
                        }
                });
                return availAcc;
            }, []);

It works!

PD: if, example your run "ionic cordova build ios" and device "iphone" is conected to mac. the change apply (line 54) is delete. then you must apply it again.

[kashban]

@waflessnet Once my PR is merged and released with the next major version the change will be permanent. It even considers both json formats, so it will be backward compatible.

[felimoles]

in xcode > 10 dont work :(

[kennybky]

I had this same problem, but I found a solution. I don't know if it would work for others but I should probably share it in case.
I uninstalled then reinstalled ios platform.
I ran npm update.

Note: I am using cordova without ionic

Cordova: 8.1.2 (cordova-lib@8.1.1)
ios-deploy: 1.9.2
xcode: 9.4.1

[kashban]

Shouldn't happen anymore with XCode 10.1. Apple reintroduced the former availability property and added a new boolean one called isAvailable.

This accepted merge request takes care of both and will be in the next major release: #451

[Ramprasathselvam]

K-MacBook-Pro:projectname2.1.7(2.1.7.3) K$ cordova build ios
Cannot read property 'toLowerCase' of undefined

any solution for above issue.

[joeldhenry]

this started happening on xcode 10.2.1 and i have no solution to get it working again :(

[janpio]

Create a new issue with all the ncessary information please. Thanks.

[lucasgalli]

it's happening in Xcode 10.2.1 and i didn't find any solution.

[JillevdW]

It just happened to me with Xcode 10.2, running on the MacOS Catalina beta. I fixed it by slightly altering the answer @waflessnet gave. Replace the availableDevices function in platforms/ios/cordova/lib/list-emulator-build-targets with the following:

var availableDevices = Object.keys(devices).reduce(function (availAcc, deviceCategory) {
    var availableDevicesInCategory = devices[deviceCategory];
    availableDevicesInCategory.forEach(function (device) {
        if (device && device.name === deviceType.name.replace(/\-inch/g, ' inch') && device.isAvailable == true) {
            availAcc.push(device);
        }
    });
    return availAcc;
}, []);

[lucasgalli]

I don't know why but I had already tried and just worked it after that I reinstall the Xcode, anyway now it's working, thanks a lot @JillevdW and @waflessnet.

[Matttaylor8910]

Why is this closed? This still happens with the latest cordova release installed

this solved my problem!
Thanks!!

[ahmadalfy]

I have cordova 9.0.0 (cordova-lib@9.0.1) and xCode Version 11.0 (11A420a). Still facing this issue

[renatoflorencia]

I am experiencing the same problem after updating xcode.
My current project has the following versions:

cordova: 8.0.0
ios platform: ^ 4.5.5
xcode: 11.0
ios version: Mojave 10.14

[brodycj]

Guys please report this kind of thing in a new issue with a reproducible example ([1]) as we do not support discussions in closed issues.

[1] https://stackoverflow.com/help/minimal-reproducible-example

[brodycj]

No more discussion on this issue please. Please raise a new issue with the reproducible example.

At this point the maintainers to not have time to actively support use with Ionic. Please consider using Capacitor for Ionic, since Capacitor was designed to work more smoothly with Ionic.

I am now locking this issue as resolved.
