Free Up Space on macOS (for React Native iOS Developers)

React Native iOS developers running out of space on your MacBook? Here are a few places specific to React Native iOS resources that you can check to free up some space. Start by going to System Preferences > General > Storage to see how much space you have. 

 

These tips are specific to React Native iOS resources. For freeing up even more space, click the Info icon next to other areas shown in System Preferences > General > Storage.

First, check if there are any emulators you no longer use. In the Storage screen, click the Info icon next to Developer. Scroll down to iOS Device Support and delete any unused emulators.


Next, check your Xcode Caches. In the Storage screen click the Info icon next to Developer. If you delete Xcode Caches, next time you open a project in Xcode it might take a few minutes while it re-indexes, but its worth it if you need to temporarily free up space.


Next, scroll down and check your Project Archives. If you want to check the file size of each archive individually before deleting, skip to the next step. But if you don't care to keep any of the archives that you've already deployed to the App Store, then Delete them all from here.


To check the size of individual archives before deleting them, launch Xcode and click Window > Organizer from the menu bar. Then choose an app at the top left. Right-click a row in the Creation Date Column and choose Show in Finder. Check the file size in Finder.


Finally, check how many instances of Hermes are installed. In System Prefs > General > Storage, click the Info icon next to Documents. Click a Hermes row and mouse over the path at the bottom to see the project using it. More on Hermes in the next post.


If you don't like the file size of Hermes, either delete the file(s) shown in the previous post for a temporary win, (making sure to run pod install on your project's ios folder next time you work on it), or switch back to JavaScriptCore if it suits your project's needs. 

Thanks for reading. I hope that with these tips you are able to free up some space on macOS.

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.

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
