Compared: Xamarin vs Xcode - iOS App Size and Startup Speed

In Xamarin I created a Single View App targeted for iOS and Android with a Shared Library. I changed the scheme to Release and removed the button click logic from ViewController.cs since Xcode's doesn't start with any button click logic. I confirmed that debugging was not enabled by putting a breakpoint in the ViewDidLoad() event, and it never hit that breakpoint. The deployment target was set to iOS 9.2.

In Xamarin I created a Xamarin.Forms App targeted for iOS and Android with a Shared Library. I changed the scheme to Release. I confirmed that debugging was not enabled by putting a breakpoint in the App() method, and it never hit that breakpoint. The deployment target was set to iOS 9.2.

In Xcode I created a Single View App using Swift targeting Universal devices. I opened the Run scheme, changed it to use the Build Configuration of Release and unchecked Debug Executable. Under Options I unchecked Core Location, XPC Services, View Debugging, and Queue Debugging. I also added a UIButton to Main.storyboard since Xamarin's starts out with a button on the storyboard. I confirmed that debugging was not enabled by putting a breakpoint in the viewDidLoad() event, and it never hit that breakpoint. The deployment target was set to iOS 9.2.

In Xcode I created a Single View App using Objective C targeting Universal devices. I opened the Run scheme, changed it to use the Build Configuration of Release and unchecked Debug Executable. Under Options I unchecked Core Location, XPC Services, View Debugging, and Queue Debugging. I also added a UIButton to Main.storyboard since Xamarin's starts out with a button on the storyboard. I confirmed that debugging was not enabled by putting a breakpoint in the viewDidLoad() event, and it never hit that breakpoint. The deployment target was set to iOS 9.2.

File Size on my iPhone 6 Plus running iOS 9.2.1 (13D15)
  • Xamarin Native:  8.6 MB
  • Xamarin Forms: 32.9 MB
  • Xcode Swift: 17.0 MB 
  • Xcode Objective C: 340 KB 
Startup time before the main storyboard is displayed on my iPhone 6 Plus running iOS 9.2.1 (13D15)
  • Xamarin Native: Less than 1 second (with a Xamarin branded launch screen before that)
  • Xamarin Forms: Less than 1 second (with a Xamarin branded launch screen before that)
  • Xcode Swift: Less than 1 second (with a blank white launch screen before that)
  • Xcode Objective C: Less than 1 second (with a blank white launch screen before that)
I was using Xcode 7.2.1 (7C1002) and Xamarin 5.10.2 (build 56)

Parameters Sent by TinyWebDB in App Inventor for Android

TinyWebDB is a component in App Inventor for Android that lets your app communicate with a web page in order to set or retrieve values, rather than storing them on the phone itself. I wanted to know what the TinyWebDB component sends to the web page when it tries to set or retrieve values, so I used Kodingen this morning to write a PHP script that takes the form fields and values sent to the page and writes them to a file. Here is what I found: TinyWebDB.StoreValue sends these parameters: tag value TinyWebDB. GetValue sends this parameter: tag So if you write your own PHP page for TinyWebDB to connect to, you can know if TinyWebDB is trying to store a value if the "value" key exists in the $_POST array. If the "value" key doesn't exist in the $_POST array then you know that TinyWebDB is only trying to retrieve the value for the given tag. As an alternative to using the method outlined by Google , you could use TinyWebDB with your own script written in an...

Adobe® Flex® Combobox: Selecting an Item Without Using SelectedIndex

In Adobe Flex, in order to select an item in a ComboBox, you use the .selectedIndex property. However, there might be times that you want to specify the item to be selected based on something other than it's position in the list. I have found two potential solutions: ComboBox2 from Ben Forta, Flex evangelist, is a ComboBox component which allows you to specify a "selectedValue" property.   VAComboBox  from Codieron, LTD.
