TFS is not working properly by Appcelerator studio. I mean even the most basic stuff is not working with this framework, React Native is 100 times better.

I’ve used Titanium in some project and it was not that bad.
Decent use of js and commonjs is required and either being aware of target platform limitations & features.
Basically if you know enough of native mobile apps, Titanium is great.

Debugging can be complex and the debugger is limited. Again a lot depend on how the code is structured.

With Tishadow the development is fast and satisfying.

I remember making a tableview and in the end it was so slow that I desperately created a custom tableview and put it in a webview. I got blazing performance after doing so. The memory management in Titanium sucks so hard I cannot even begin to describe it.

Also the forum and everybody on it is constantly down playing the bad things, like oh you just have to do it like this and in the end it doesn’t work.

It has major flaws. The funny thing is, people claim it is native, it is freaking not native! It has a custom view engine for crying out loud. It sucks really really hard. They claim it is css based, it is not. The attribute names might be css like, but it is not even close to CSS, because it renders differently. The positioning of the views is completely different than that of CSS. So you have to learn that first before you can effectively use it, and there is NO documentation on it, other than a few crappy blog items from people being paid by some share holder.

Bug fixes are terribly slow. If you encounter a bug in the Titanium framework, you better not expect to get any help soon. Some developer will look into it next month and it will be available in the next release. In the real world you don’t have a freaking month to waste! Time is money. Also, issues remain open for months and sometimes won’t get fixed at all. It is so slow, it is painful and very frustrating.

I have a question for all politically right Titanium users; why would you invest in something that is created by one crappy company over for ex. Phonegap, which is HTML5, JS and CSS based. Technologies that have been developed for years. It won’t make any sense, not to go for Phonegap (or go fully native). These technologies have been optimized to perform in a web browser. And looking at skills, most developers have these skills already. This won’t put your projects at risk.

My opinion is that Titanium is just too much of a good thing, it is just trying to implement all native features in one overrated framework. It doesn’t make sense. Phonegap on the other hand is just the things that need to be implemented, like camera access etc. are available through javascript. The rest is just browser based and has good performance compared to titanium. Speed of implementation is much faster with Phonegap. Custom layouts are easier to make compared to the crap view rending engine of Titanium. It is a waste of time!

Because the company still exists, doesn’t mean it is a good framework or company. It just has a share holder that doesn’t want negative attention or too much annoyed users on the forum.
