I have read this to learn about ように:
<http://www.guidetojapanese.org/learn/grammar/surunaru>

Part - 1 Going by the definition of よう which is more like "appearance/manner",
I don't quite get how the constructions are made in which ように has more of an
interpretation of "so that". I have read its similar counterpart, ために and the
difference between them ([Difference between ために and
ように](https://japanese.stackexchange.com/questions/12450/difference-
between-%E3%81%9F%E3%82%81%E3%81%AB-and-%E3%82%88%E3%81%86%E3%81%AB)), but I
still can't arrive how from the literal meaning of appearance or like, we can
reach a meaning like "so that"

Ex 1: 速く泳げるように、毎日練習しています。

Part - 2 As per my understanding, we need to use ように to allow us to modify a
verb with another verb. But when we use the negative form of the verb in plain
form (ない form), it is more like an adjective. So why do we use "ーないように some
other verb".

Ex 1: 忘れないようにつけてあるんです（丸をつける）- I have marked the circles so that I don't
forget.

Ex 2: 工場ができてから、この近くの海では泳げなくなりました。 Since the completion of the factory, I was
not able to swim in the nearby sea.

As example 2 shows ーなくなります is also used. What difference to the meaning will
ーないようになる add?

Thanks for any help.

question
grammar
using ように pattern to mean "so that" and its use in negative verbs
You may be letting the "translated" English words get in the way of your
understanding a little too much. Hard as you may stare at the words
"appearance/manner", they will not magically turn into a "so that" in your
English-speaking mind. Point is that will not happen even in my Japanese-
speaking mind, either.

Japanese is all about context. 「よう」 could mean "appearance/manner" all by
itself without any context but it takes the right context, namely at least two
mini-sentences, for 「よう」 or 「ように」 to mean "so that".

「(A desired state/result) + ように + do A.」 means "Do A so that (a desired
state/result) occurs."

In the sentence 「速く泳げるように、毎日練習しています」, 「速く泳げる」 is the desired state and
「毎日練習しています」 is the "do A" part in my explanation above.

Moving on to the negative, please remember that the structure is exactly the
same as the affirmative.

In the sentence 「忘れないように丸をつけてあります。」, 「忘れない」 is the desired state and 「丸をつける」
is what you do so that the desired state of 「忘れない」 could be obtained.

Finally, the sentence 「工場ができてから、この近くの海では泳げなくなりました。」 is another story because
it does not contain 「ように」. 「なる」 is a magic verb in Japanese and we use it many
times everyday or I would even say "many times every hour". It expresses a
change of state.

Former state: 「この近くの海では泳げた」

Present state: 「この近くの海では泳げない」

What brought about the change? It is the building of the factory. And what is
the magic verb to describe a change of state? Yes, なる. So let's add it here.

泳げない + なる = 泳げなくなる

To change it to the past tense, it is 泳げなくなった and to make it sound polite, you
get 泳げなくなりました. Voila.

To answer your last question, it expresses a change of state/situation either
as a result (as with the case of the "swimming" sentence) or as a desired
improvement (as with the "marking/circling" sentence).
